Values:
ISO 492:2014 (table 1, table 2, table 3)
The inner rings with roller and cage assembly and outer rings of SKF single row tapered roller bearings with the same basic designation are interchangeable. The tolerance for the total abutment width T of the bearing is not exceeded if the cups and cones are interchanged.

If misalignment cannot be avoided, SKF recommends not to use basic design bearings.

The permissible angular misalignment between the inner and outer rings depends on the size and internal design of the bearing, the radial internal clearance in operation and the forces and moments acting on the bearing. As a result, only approximate values are listed here. Any misalignment increases bearing noise and reduces bearing service life.

If misalignment cannot be avoided, SKF recommends using a face-to-face arrangement.

Any misalignment increases bearing noise and reduces bearing service
life.

Values: ANSI/ABMA Standard 19.2-1994 (table 6)
Deviating width tolerances for cups and cones are identified by a designation suffix (table 7).
The inner rings with roller and cage assembly and outer rings of SKF single row tapered roller bearings with the same basic designation are interchangeable. The tolerance for the total abutment width T of the bearing is not exceeded if the cups and cones are interchanged.

Obtained after mounting, depending on adjustment against a second bearing.

Misalignment

TQ-line bearings (designation suffix Q):

≈ 2 to 4 minutes of arc
